A portrait of Siobhan using 3 flash guns off camera. Two speedlites were on the model with shoot through brollies and the third flash was used to light the background. By using the 2 lights on the model I was able to reduce the power on each flash gun and the third flash on full power was enough to give a nice white background.I know some branded flash units are very expensive but so long as you have some manual control cheaper branded units like Yongnuo are ideal.
